PHILADELPHIA, Sept. 2, 2026 /PRNewswire/ -- Berger Montague PC, a leading national plaintiffs' law firm, announces a class action lawsuit against Hyliion Holdings Corp. (NYSE: HYLN) ("Hyliion" or the "Company") on behalf of investors who purchased or acquired Hyliion securities during the period from May 12, 2026 through June 23, 2026 (the "Class Period"). The deadline to apply for lead plaintiff is October 27, 2026.
Q&A
What is this lawsuit about?
This lawsuit concerns whether Hyliion and certain of its officers misled investors about the significance and prospects of the Company's purported data center partnership with VFG Holdings, LLC ("VFG").
On May 12, 2026, Hyliion issued a press release announcing that it had entered into a non-binding letter of intent ("LOI") with VFG establishing a strategic partnership to deploy up to 250 KARNO Power Modules, or approximately 50 megawatts of power generation capacity, at VFG's data center sites over the next five years.
On May 19, 2026 – within days of the VFG announcement – Hyliion disclosed in SEC filings that CEO Thomas Healy, CFO Jon Panzer, and several other Company insiders had sold shares pursuant to 10b5-1 trading plans.
Then, on June 23, 2026, Pelican Way Research published a report entitled "Hyliion: A Glorified Science Project Who Has Continuously Failed to Meet Expectations And Is Now Throwing Around A Meaningless Deal." The report alleged that the VFG LOI was a sham because VFG had only been formed in January 2026, appeared to have only about four employees, operated a barely functioning two-page website with no listed address, and had posted nothing on LinkedIn other than the announcement of its deal with Hyliion. On this news, Hyliion's stock price fell $1.27 per share, or 17%, to close at $6.10 on June 23, 2026. The following day, Hyliion's stock price fell a further $1.18 per share, or 19%, to close at $4.92 on June 24, 2026.
Who is Hyliion?
Hyliion, headquartered in Cedar Park, Texas, is a developer of modular power plant technology, including its KARNO Power Module.
